    摘要： An object of the present invention is to provide a scroll compressor capable of three-dimensional compression, which can prevent performance deterioration and performance variation due to gas leakage occurring on an outer peripheral side of a step portion of a spiral wrap and can achieve performance stabilization and performance improvement. In a scroll compressor configured to be capable of three-dimensional compression in a circumferential direction and a height direction of spiral wraps, in which top surfaces and bottom surfaces of spiral wraps (25B and 27B) are provided with step portions (25E and 27E) and the wrap height on the outer peripheral side of the step portion is made higher than the wrap height on the inner peripheral side, back-pressure introducing portions (55 and 57) where gaps between the back surfaces at step-portion ends of tip seals and groove bottom surfaces of tip seal grooves are made larger than a gap at the other portion are formed between the step-portion ends of tip seals (51 and 53) provided on top surfaces (25G and 27G) on the outer peripheral side of the spiral wraps and tip seal grooves (25L and 27L) to which the tip seals are fitted.

    摘要： To provide a scroll compressor capable of reducing a noise occurring in a pin-and-ring type self rotation preventing mechanism and improving compression performance. In a scroll compressor comprising: a fixed scroll member (25) and a revolving scroll member (27); a driven crank mechanism (55) for driving the revolving scroll member (27) to revolutionary turn; and a pin-and-ring type self rotation preventing mechanism (33) provided in plural places for preventing self rotation of a revolving scroll member (27), at least one of the self rotation preventing pin (63), the self rotation preventing ring (65) and the self rotation preventing ring hole (27D), which form the pin-and-ring type self rotation preventing mechanism (33), being provided with an orbit correction part (67) for reducing a maximum displacement R in a direction of self rotation of the revolving scroll member to smooth a change of an orbit of the revolving scroll member in changing a pin and a ring in a section of prevention of self rotation by means of a corresponding pin and ring part.
